摘　　要：基于HLA/RTI和STK,设计了卫星星座导航与控制分布式仿真系统。仿真系统中每颗卫星均由单独的计算机模拟,可真实地反映星座的运行情况,更好地模拟星间链路;卫星轨道精确外推、星间链路优化、基于基准星和星间距离测量的分布式导航以及基于相对轨道根数的星座绝对站位保持等关键技术也融入到系统中;仿真系统还具有直观的二维、三维场景和曲线动态可视化演示功能。结合具体的W alker星座实例,仿真星座稳定运行180天,系统运行结果表明所设计的仿真系统及采用的关键技术能够满足仿真与评估的需求。另外,在一定程度上该仿真系统还支持其它卫星星座的仿真与评估。A distributed simulation system for navigation and control of satellite constellation is designed,which is based on HLA/RTI（High Level Architecture/Run-time Infrastructure） and STK（Satellite Tool Kit）.In order to present the operation conditions of real satellite constellation and factually simulate inter-satellite links,the sole computer is applied to simulate each satellite in this system.Several key technologies are employed,such as precise satellite orbit extrapolation,the optimization of inter-satellite links,the distributed navigation algorithms based on reference satellites and inter-satellite distance,satellite constellation absolute station keeping that is based on relative orbit elements and so on.The vivid two-dimensional and three-dimensional scenario and curve presentation are provided as well.A specific walker satellite constellation,an example in this system,can run 180 days stably.The simulation results show that the key technologies proposed in this paper are valid.The simulation system can also support the simulation and estimation of other satellite constellations.
